Virtual Machines can be moved to and from VMware HCX-enabled data centers using multiple migration technologies.
VMware HCX Bulk Migration
This migration method uses the VMware vSphere Replication protocols to move the virtual machines to a destination site.
The Bulk migration option is designed for moving virtual machines in parallel.
This migration type can set to complete on a pre-defined schedule.
The virtual machine runs at the source site until the failover begins. The service interruption with the bulk migration is equivalent to a reboot.
VMware HCX vMotion
This migration method uses the VMware vMotion protocol to move a virtual machine to a remote site.
The vMotion migration option is designed for moving single virtual machine at a time.
Virtual machine state is migrated. There is no service interruption during the VMware HCX vMotion migration.
VMware HCX Cold Migration
This migration method uses the VMware NFC protocol. It is automatically selected when the source virtual machine is powered off.
VMware HCX Replication Assisted vMotion
VMware HCX Replication Assisted vMotion (RAV) combines advantages from VMware HCX Bulk Migration (parallel operations, resiliency, and scheduling) with VMware HCX vMotion (zero downtime virtual machine state migration).
VMware HCX OS Assisted Migration
This migration method provides for the bulk migration of guest (non-vSphere) virtual machines using OS Assisted Migration to VMware vSphere on-premise or cloud-based data centers. Enabling this service requires additional HCX licensing.
